SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Kotlin applications often struggle with reliable and idiomatic HTTP client communication. This skill provides a structured approach to using the Ktor client to talk to REST services, handle serialization, and manage authentication and errors.

Core Features & Use Cases

  • Ktor HttpClient setup with CIO engine and ContentNegotiation for JSON.
  • Built-in support for authentication, timeouts, retry logic, and error handling.
  • Use Cases: consume REST APIs, call microservices, and integrate with backend services from Kotlin apps.

Quick Start

  1. Add Ktor client dependencies to your Kotlin project (ktor-client-core, ktor-client-cio, ktor-client-content-negotiation, kotlinx-serialization, ktor-client-logging).
  2. Initialize HttpClient with CIO and ContentNegotiation, then perform a GET/POST request to a sample endpoint.
  3. Use the Backend API pattern to organize requests and error handling.
